METAL SHE'ET-PILING.

Specification of Letters Patent.

Patented J'une 26, 1906.

Application filed December 4, 1906. Serial No. 290,057.

Be it known that I, RICHARD H. STEVENS, of Munhall, Allegheny county,Pennsylvania, have invented a new and useful Im rovement in MetalSheet-Piling, of which t e fol lowing is a full, clear, and exactdescription, reference being had to the accompanying drawings, in whichFigure 1 is aplan view of a piling structure, showing the manner inwhich interlocking sheet-piling constructed according to my invention isassembled to form an inclosure and also showing the manner in whichthecorners are turned in a rectangular inclosure. Fig. 2 is aperspective view, on a larger scale, of the end of a single pile as itis formed in accordance with my invention.

My invention re ates to sheet-piling constructed of metal, and moreparticularly to metal sheet-piling in which the members interlock withone another to form an inclosure.

The object of my invention is to provide an interlocking shape which canbe easily and cheaply manufactured from ordinary rolledmetal plates.

Another object of my invention is to provide a pile in which theuse ofrivets, bolts, and similar securing means is avoided.

In the drawings, 2 represents the interlocking shape, which consists ina web portion 2 and reversely-coiled ed e portions 2 The edge portions 2are curved so as to form an interlocking connection or joint between thesimilar curved edge portions 2 of the ad joining piles. When driving thepiles, a suitable rod or 1 bar 3' is preferably driven with the ile inthe 'o ening formed between the curve edges of t e piles which, afterbeing driven into the ground, may remain in place or may be withdrawn,as is desired. In the use of the piles to form a water-tight inclosurethe rods 3 are withdrawn, and the opening left by their removal may befilled with a suitable packing material. The piles may also be drivenwithout employing the rods.

In the manufacture of the piles I preferably take what are known asuniversal plates, and by passing through suitable forming means curve orcoil the edges of the plates into the shape as shown in the drawmgs.

The advantages of my invention will be apparent to those skilled in theart. By constructing'the piles from a plate great strength and stiffnessis secured with a minimum weight of material.

I claim 1. An interlockin metal sheet-pile having a web' and reversey-curved'edge portions adapted to interlock with the curved edges ofsimilar piles; substantially as describe 2. In metal sheet-pilin a sha ehaving a straight webportion an curved ed e portions the edges being searated from t e Web by grooves; substantia y as described.

In testimony whereof I have hereunto set my hand.

RICHARD H. STEVENS.
